Gateway raises an exception when shut down

[agronholm]

INFO:py4j.java_gateway:Callback Server Shutting Down
ERROR:py4j.java_gateway:Error while waiting for a connection.
Traceback (most recent call last):
File "/home/alex/virtualenv/etikettu/local/lib/python2.7/site-packages/py4j-0.7-py2.7.egg/py4j/java_gateway.py", line 909, in run

File "/usr/lib/python2.7/socket.py", line 202, in accept
sock, addr = self._sock.accept()
error: [Errno 22] Invalid argument

All I did to get this was gateway.shutdown() some time after it had started up.

This is in the log right (the exception is not propagated to the client's code)?

There is no way to prevent the exception to be raised (a socket is closed while listening), but the log level should be debug or something like that since this is an expected exception.

Thanks for noticing this inconsistency!

[agronholm]

Right. Perhaps this specific exception should be silently ignored?

I'll close this issue because I believe the problem was adressed in issue #92 . Please open a new issue if there are other messages that need to be tuned down.
